Even/odd vertices & tracing of edges
Find the number of even nodes
A) 2
B) 4
C) 3
D) 5
A Node is a continuous curve that crosses itself. So when the question asks you to find the number of even or odd nodes, you have to look at any given point and count how many lines or pathways are connected to it.
This point is an even node because it only has two lines or pathways connected to it. So that’s one even node for sure.
This point is an odd node because it has three lines connected to it. Three is an odd number so this doesn’t work.
This point works because it has two lines connected to it. Two is an even number so this definitely works. This would work if there were four, six, or even twelve lines connected to the point. As long as the number of lines are even it would work.
This point doesn’t work because there are an odd number of lines connected to this point. Therefore making this an odd node.
This node is even because it has two lines connected to it so this works.
Now that we have covered all of the nodes we now know what the answer is.
That is how you figure out on how to find the number of even or odd nodes in a problem like this one. Good luck everyone.
